Hello foamers,
I tried to simulate a naca 63-215 profile with an o - grid. I'd like to us ethe komegaSST model but anytime the velocity explodes and the residuals don't decrease. I have a Re number of 3*10⁶. Here are my boundaries:

Inlet: U=300, k=0.001, omega= 0.001, nut=calculated, p=zeroGradient
outlet: U=zerGradient, k=zeroGradient, omega=zeroGradient, nut=calculated, p=0
wall: U=0, k=kqrWallFunction 0.001, omega=omegaWallFunction 0.001, nut=nutWallFunction 0, p=0

Can anybody say if this are the right boundaries? I already tried with kepsilon and SpalartAllmaras but without success.

Thank you in advance
